When working on a computer , there are quite a few crucial functions that you need to perform on a daily basis and that includes, copying, renaming, moving or deleting files. However, while performing these functions, you may encounter an error, “Invalid MS-DOS Function“.
This is a file system error that is known to impact only the file functionality. However, it can be frustrating as it restricts your usage. Even when you are trying to move a file from a drive with NTFS format to a drive with FAT32 format, you can encounter the error. However, the good thing is, this can be fixed. Let’s see how.
Solution: Using Registry Editor
Step 1: Navigate to the start button on your PC and type Registry Editor in the search box. Left-click on the result to open the Registry Editor window.

Now, on the right side of the window, right-click on an empty area and select New in the right-click menu. From the sub-menu, select DWORD (32-bit) Value.
